US lawyers bid to free Irish mob boss James Bulger
Boston mob boss James 'Whitey' Bulger's case is returning to a US court - minus the notorious gangster.
Bulger and many members of his gang were of Irish descent, and helped arm the IRA in the 1980s.
The 1st US Circuit Court of Appeals in Boston will hear arguments from Bulger's lawyers, who are trying to overturn his racketeering convictions.
Bulger's lawyers contend his right to a fair trial was violated when a judge barred him from telling the jury about his claim that a federal prosecutor promised him immunity. The judge found that Bulger offered no hard evidence of an immunity deal.
Prosecutors say the evidence overwhelmingly showed Bulger's guilt and he should not get a new trial.
Bulger (85) was convicted in 2013 of participating in 11 murders in the 1970s and 80s. He is serving a life sentence in Florida and will not be present for the proceedings. One of those Bulger was found guilty of murdering was IRA smuggler John McIntyre, a crewman on the Valhalla, a boat used to run guns to Ireland.
